How can I get into the GA pit at Tsongas Arena, Lowell MA?

Some friends and I want to go to the A Day to Remember and Rise Against concert at the Tsongas Arena on Feb 1st. But of course, us being us, we are just getting tickets now. It seems like all tickets for the GA pit are sold out. I've found resale tickets online but those are like 3 or 4 times face value so I'd like to avoid buying those. There are seat tickets available though. So what I'm thinking is we could do one of 2 things. The first would be to just walk into the GA pit, I mean idk how the employees there can check everyone in so how hard could it be? The other option, in case they somehow do have a way to make us get to our proper seats would be to just hop down into the pit since pictures Ive seen online looks like this could be doable. So anyone been to the tsongas and know if I'll be able to get into the pit?|||Just compare this ticket price visit this site http://www.ticketnetwork.com/tix/rise-ag鈥?/a>|||Try to check a lot of available ticket offers here http://www.gigographya.com/concerts/rise鈥?/a> hope it helps u.
